Abstract (en)

A honeycomb type gas separating membrane structure (1) is used for separating or supplying a specified gas from a mixed gas. The gas separating membrane structure (1) has a honeycomb unitary structure and is a dense body comprising an oxide having a brownmillerite structure. The honeycomb type gas separating membrane structure does not require a support for supporting a gas separating membrane, can provide a large membrane area, and can reduce costs because its production process is simple. <IMAGE>
